ROLL-FELIX! HOLDER.

Specification of Letters Patent.

Patented May 11, 1909.

T 0 all whom it may concern:

Be it known that I, LOUIS S. Burner, cit-i zen of the United States,residing at South Tacoma, 1n the county of Pierce and State 5 of Vlashington, have invented certain new and useful Improvements inRoll-Film Holders, of which the following is a specification.

The present invention relates in genera to photography, and moreparticularly to a novel film holder which is peculiarly constructed sothat it can be readily applied to a camera or removed therefrom, therebyenabling the camera to be focused before each exposure, should this befound desirable.

The invention further contemplates a film holder which can be readilyapplied to the cameras now in common use, which is simple andinexpensive in its construction, and which is so designed as to admit ofthe films being quickly inserted in position therein or removedtherefrom.

F or afull understanding of the invention and the merits thereof andalso to acquire knowledge of the details of construction and the meansfor effecting the result, reference is to be had to the followingdescription and accompanying crawings, in which:

Figure 1 is a perspective view of a camera provided with a film holderconstructed in accordance with the invention; Fig. 2 is a longitudinalsectional view through the film holder when detached from the camera;Fig. 3 is a transverse sectional view on the line 33 of Fig. 2; and Fig.is a view similar to Fig. 2 with the ends of the film iolder swungrearwardly.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The main frame of the film holder embodying the present inventioncomprises a back 1 and side flanges Qwhich extend along opposite edgesof the back and project be yond the ends thereof as indicated at 2*, thesaid projecting ends of the flanges being curved forwardly forengagement with the body portion of a camera in the usual manner.Carried by each end of the back 1 is a swinging end 3, the said endspreferably having a substantially semi cylindrical formation and beingdesigned to receive the usual film spools. In the preferred constructionthese swinging ends are hinged to l the main frame by means of acovering of leather or similar material which is applied to the back andends, the said covering serving to insure a light proof joint betweenthe members. Each of the swinging ends 3 is provided at both the top andbottom thereof with a disk or plate l and these disks are perforated toreceive the usual ,spindles upon which the film spools are mounted. Itwill also be observed that the inclosing sides of each of the swingingends. is formed of two spaced walls and that a curved slide 5 isreceived between these spaced walls. These curved slides are designed tobe drawn outwardly so as to fit over the film spools when the device isin use and to protect the film upon the spools from light. The outerends of these curved slides are prorided with lips 6 adapted to engage amain slide '7 inserted through a slot in one of the side flanges 2. Thefilm is 1 designed to be wound from a spool in one of the swinging ends3 upon a spool in the opposite swinging end and to pass over the a back1 between the said back and the black slide 7, spring strips 8 beingutilized for 1 forcing the film against the back and preventing it fromspringing out into the path of the slide. Opposit-e enos of the filmholder are )TOVlClBCl with spring catches 9 by means of which it can beapplied to a camera and held in position thereon the same as theordinary film holders now in common use. When the black slide 7 iswithdrawn, the films may be exposed in the usual manner. However, shouldit be desired to focus the camera before making an exposure, it issimply necessary to first insert the black slide 7 and then to removethe film holder from the camera, the said black slide overlapping thelips 6 of the curved slides 5 and cooperating with the frame andswinging ends to form a light proof chan'lber for the film and toprotect it from the light. Owing to the fact that the ends 3 are mountedso as to swing rearvv'ardly the film spools can be readily inserted inposition therein or removed therefrom as desired and the camera can bequickly and conveniently loaded or unloaded in the usual manner.

Should it be desired to employ a plate instead of a film, it will beobvious that when one of the ends 3 is swung rearwardly a plate holdercould be readily inserted between the back 1 and the slide 7.

Having thus described the invention, what is claimed as new is:

1. In a device of the character described, the combination of a frame,swinging ends applied to the frame, and a slide mounted upon the frameand cooperating with the swinging ends to provide a light proof chamberfor a sensitized film.

2. In a film holder, the combination of a frame, swinging ends appliedto the frame, slides upon the swinging ends, and a main slide mountedupon the frame and engaging the slides of the swinging ends, the saidmain slide cooperating with the frame and swinging ends to form a lightproof chamber for the reception of the film.

3. In a film holder, the combination of a frame, ends for the frame,curved slides mounted upon the ends, and a main slide mounted upon theframe and adapted to engage the curved slides of the ends, the said mainslide coiiperating with the frame and ends to form a light proof chamberfor the reception of the film.

l. In a film holder, the combination of a frame, swinging ends of asubstantially semicylindrical formation applied to the frame and adaptedto receive the usual film spools, curved slides applied to the swingingends and formed at their outer ends with lips, and a main slide mountedupon the frame and adapted to engage the lips of the curved slides, thesaid main slide cooperating with the frame and ends to form a lightproof chamber for the reception of the film.

5. In a film holder, the combination of a frame, comprising a back andside flanges, the said side flanges projecting beyond opposite ends ofthe back and serving to engage a camera, swinging ends applied to theback and designed to receive the usual film spools, curved slidesmounted upon the swinging ends, and a main slide mounted upon the sideflanges of the frame and adapted to enthe before mentioned curvedslides, the said main slide cooperating with the frame and ends toprovide a light proof chamber for the reception of the film.

In testimony whereof I affix my signature in presence of two witnesses.
